Description

Technical Field

[0001] The utility model relates to the field of construction wire-laying tools, in particular to a construction wire-laying frame. Background Art

[0002] The layout of the civil construction stage of the construction project is roughly divided into the stages of building positioning, earth excavation, foundation construction and main construction layout. The layout after the start of the housing construction project is mainly based on the building planning positioning map, and finally a number of positioning piles are formed at the construction site. The purpose of the entire layout process is mainly to find the correct positioning and spread lime dividing lines along the baseline to facilitate construction.

[0003] The common way of paying out the wire is to pay out the wire manually, pull the wire end off the wire drum, roll the wire drum to continuously pull the wire to the designated point, and tie it to the positioning pile. Therefore, during the wire paying out process, two people are required to cooperate, which is cumbersome. In addition, after the wire is pulled out, it is not convenient to fix the end of the coil on the wire drum, and the released wire is not tight, which is easy to cause deviation.

[0021] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0022] In the accompanying drawings, direction a is the plumb direction, and direction b is the horizontal direction.

[0023] See also Figures 1 to 5 The figure shows a construction pay-off frame, which includes a base 1, and the base 1 is connected to a rotating base 2 for rotation along the plumb direction. The base 1 is provided with a first locking bolt 102 for locking the rotation of the rotating base 2. The first locking bolt 102 is as shown in FIG. Figure 2 The thread shown is connected to the base 1 and extends inward along the threaded hole to contact the rotating base 2, thereby limiting the relative rotation between the base 1 and the rotating base 2.

[0024] like Figure 1 The rotating seat 2 is provided with a bracket 201, and a wire drum 3 for winding the construction wire is connected to the bracket 201 in a horizontal rotation direction, and the rotating shaft 301 of the wire drum is rotatably connected to the shaft seat 2011 welded on the bracket 201. The wire drum 3 is arranged on the rotating frame, and during the wire laying process, the wire laying direction can be adjusted by rotating the rotating seat 2 and further rotating the wire drum 3, thereby improving the wire laying efficiency.

[0025] The bracket 201 is provided with a second locking bolt 4 for locking the rotation of the wire drum 3. Specifically, the second locking spiral is threadedly connected to the shaft seat 2011. The rotating shaft 301 of the second locking bolt 4 extends radially inward, can contact the rotating shaft 301 and limit the relative rotation of the wire drum and the bracket 201. In the process of releasing the wire, when the wire drum 3 rotates in the reverse direction to tighten the wire, the wire drum 3 rotates forward to loosen the construction wire and reduce the loose winding of the wire head.

[0026] A hand wheel 302 is provided on one side of the wire drum 3, and the hand wheel 302 is fixedly connected to the rotating shaft 301 of the wire drum 3. During use, the wire drum 3 can be rotated by holding the hand wheel 302 to release and reel in the construction wire, thereby improving the construction routing efficiency. At the same time, a single person can also perform the wire release operation, which can save a certain amount of labor.

[0027] like Figures 1 to 4 The wire drum 3 shown in the figure is provided with a roller assembly 5 and a wire pressing assembly 6 on one side. The roller assembly 5 and the wire pressing assembly 6 are fixedly mounted on a support plate 2012 on a bracket 201. The free end of the construction wire is pulled out from the wire drum 3, and passes through the roller assembly 5 and the wire pressing assembly 6 in sequence to extend outward. The wire pressing assembly 6 can press the connection end of the construction wire and the wire drum 3 (or the other end opposite to the free end) and fix it. This prevents the connection section of the construction wire from loosening during the wire stretching process because it is only wound on the wire drum 3, and also prevents the connection end from being wound in a disordered manner along the axial direction of the wire drum 3. The free end can be continuously straightened, which is convenient for straightening the construction wire, improving the routing accuracy of the construction wire, and improving the subsequent marking procedure.

[0028] like Figure 4 The roller assembly 5 shown includes a roller seat 500 fixedly mounted on a support plate 2012, and a first roller 501 and a second roller 502 which are parallel to each other are rotatably connected on the roller seat 500. The first roller 501 and the second roller 502 are both provided with a V-shaped groove 503 which matches with the construction wire. During the wire laying process, the construction wire is passed through the V-shaped groove 503, and the first roller 501 and the second roller 502 are rotated, so that the construction wire can be guided to a point during the wire laying process to be released, thereby improving the accuracy of the wire laying. At the same time, the construction wire is also guided to the middle position between the wire laying drum and the wire laying drum, so that the wire pressing assembly 6 can press the wire.

[0029] like Figure 4 , Figure 5 The wire pressing assembly 6 shown includes a pair of studs 603 fixedly connected to the support plate 2012, and a pressing plate 605 is slidably arranged outside the studs 603, and the pressing plate 605 is parallel to the support plate 2012. One side of the pressing plate 605 is connected to the support plate 2012 through a spring 602, and the other side is provided with a pair of butterfly nuts 604 threadedly connected to the studs 603, and the butterfly nuts 604 can be rotated to contact and move the pressing plate 605 downward along the plumb bob, so that the construction wire is pressed between the support plate 2012 and the pressing plate 605, so as to facilitate the straightening of the construction wire.

[0030] like Figure 5The pressing plate 605 is provided with pressing teeth a606, and the supporting plate 2012 is provided with pressing teeth b601 interlacedly meshed with the pressing teeth a606. The pressing teeth a606 and the pressing teeth b601 are both provided with cutouts 6011 matched with the construction wire. When in use, the construction wire passes through the cutouts 6011, and the pressing teeth a606 and the pressing teeth b601 interlacedly mesh with each other, thereby pressing the wire body and improving the firmness of the wire body fixation.

[0031] like Figure 1 The lower end of the base 1 is also provided with a moving wheel 101. During use, the pay-off frame can be moved to the point where the wire is to be paid out by the moving wheel 101, so that the pay-off frame can be transferred conveniently.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
